Question

Find the coefficient of range for the data $43,24,38,56,22,39,45$

• A. $0124$
• B. $0.212$
• C. $0.236$
• D. $0.436$

Answer 1

The correct option is D $0.436$

Given data is $43,24,38,56,2,39,45$.

The largest value of data is $x_m=56$

The smallest value of data is $x_0=22$

Coefficient of data $=\frac{56-22}{56+22}=\frac{34}{78}=0.4359\approx 0.436$

Hence, option D is correct.
